An example of the U.S. military’s largest amphibious craft, the LARC-LX (lighter, amphibious, resupply, cargo) came in three sizes, ranging in size from 5 ton (LARC v) to the LX, capable of transporting 60 tons from ocean to inland, across heavy seas and up inclines as steep as 60 degrees.  It remains the only amphibian in the current inventory able to enter and exit the shore through breaking surf.  Outfitted with 4 Detroit Diesel engines, twin props, and four wheel drive with two or four wheel steering, the LARC-LX could go just about anywhere and carry whatever could fit in its cavernous cargo bay. The only real limitation was its immense size - length is over 62', width is 26', and height is almost 20'!  The tires are 9' high.  With a 75' turning radius, the LARC is surprisingly agile, and this particular example was driven here in January 2005 from the Port of Nashville.
